The vowel /i/ appears in its usual range of spellings, including the letter names B, C, E, P and T. The /aɪ/ vowel is most commonly <iCe> as in bite, <y> final as in fly and sky, but is also <igh> in night, <ai> in Thai, and <uy> in buy.
Notice the homograph lied, which appears on one side in the pair lead/lied meaning told falsehoods, and on the other in the pair Lied/light where it means German song. Note the pairs emphases/emphasize and syntheses/synthesize, where a latinate plural contrasts with a verb-forming suffix. The alumnae/alumni contrast also depends on how one has been taught to pronounce latin plurals.
Since this contrast is between a simple vowel and a diphthong, it is unlikely to pose difficulties for learners.
The only mildly taboo word pairs are pee/pie and wee/why.
